The report, authored by Hugh Saddler, notes that for nine of the last 18 months, half of all electricity supplied in S.A. has been from renewable generators, including rooftop solar.This renewable generation has at times been enough to meet all of the state’s energy demand and – as AEMO has acknowledged – will be able to gradually reduce market interventions such as directing gas generators to run as more synchronous condensers come on line.“South Australia is showing Australia and the rest of the world how best to integrate new generation on a large scale,” says Saddler. “The inter-connector between South Australia and Victoria was completed more than 30 years ago, and since then South Australia has almost always been a net importer of electricity from Victoria. Now, thanks to its strong renewables leadership and uptake, it is a net exporter of electricity to Victoria for most months of the year.”“Eliminating ‘base load’ is what the transition to a low emission renewable generation based electricity supply system is doing,” the report says; “in South Australia, in the rest of Australia, and round the world. The complement to variable renewable generation is not so-called “base load” generation (a meaningless term), but energy storage in some of its many forms and spatial/climatic diversification of renewable generation.”More: South Australia “an example to the world” of how to move beyond baseload Analysis says South Australia is setting an example for renewable energy transition
